Repolarization disparity as a predictor of response to Head up Tilt-table Test in pediatric syncope.

Background: Head up Tilt-table Test (HUTT) is a practical examination of the most common type of pediatrics syncope. The electrocardiographic (ECG) changes during this test, show the autonomic defects that cause neuraly-mediated syncope in response to tilting process.

Methods: All pediatric syncope patients referred to our center in a 1-year period, were included in the study.

Fibrinogen prophylaxis for reducing perioperative bleeding in patients undergoing radical cystectomy: A double-blind placebo-controlled randomized trial.

Objective: Excessive bleeding is an important complication of radical cystectomy. We aimed to assess whether preoperative administration of fibrinogen decreases perioperative bleeding and improves the outcome of radical cystectomy.

Design: Double-blinded randomized trial with two parallel arms.

Efficacy of Oral Administration of Powder "Garlic Extract" on Lipid Profile, Inflammation, and Cardiovascular Indices among Hemodialysis Patients.

Background: Inflammation plays a prominent role in the deteriorating cardiovascular risk of hemodialysis patients. Utilization of herbal remedies, especially garlic extract, in these patients has resulted in promising improvement in lipid profile, inflammation, and cardiovascular markers.

Purpose: In this survey, we aimed to determine the effects of oral administration of powder on lipid profile, inflammation, and cardiovascular markers among hemodialysis patients.

The Effect of High-Power and Low-Power Lasers on Symptoms and the Nerve Conduction Study in Patients With Carpal Tunnel Syndrome. A Prospective Randomized Single-Blind Clinical Trial.

Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment. Various treatments have been suggested for CTS and there is no consensus on their superiority and the order of their use. Laser therapy is a non-invasive treatment method for many musculoskeletal diseases, including CTS.

Are women more susceptible to ischemic heart disease compared to men? A literature overview.

Ischemic heart disease (IHD) is known as the leading cause of death in both genders.
